pferd/CHANGELOG.md

# Changelog

All notable changes to this project will be documented in this file. The format
is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

This project has its own custom versioning scheme. Version numbers consist of
three parts (e. g. `3.1.5`).
- The first number is increased on major rewrites or changes. What classifies as
  a major change is up to the maintainers. This is pretty rare and a PFERD
  version 4 should hopefully not be necessary.
- The second number is increased on backwards-incompatible changes in behaviour.
  This refers to any change that would make an existing setup behave differently
  (e. g. renaming options or changing crawler behaviour). If this number is
  increased, it may be necessary for you to adapt your own setup.
- The third number is increased on backwards-compatible changes (e. g. adding
  new options or commands, changing documentation, fixing bugs). Updates that
  only increase this number should be safe and not require manual intervention.

We will try to correctly classify changes as backwards-compatible or
backwards-incompatible, but may occasionally make mistakes or stumble across
ambiguous situations.
